220 question....

[Paul-ish]

I had an electrician wire my garage and I was sheeting it today when a friend pointed out something to me.

I am running 2-220 outlets on 30 amp breakers.
I bought all the wire... At homedepot I asked them for 220 - 30 wire and this is what they gave me. It has 2 thick 110's ? and a ground? But no common??? It's wired into both hot sides of a double wide breaker?

Sorry I know nothing about electrical... But now my friend has me thinking I'm going to have to open my walls up and run different wire.

if the equipment,welder,table saw ect,is a 220 volt device,no neutral is required.an example of equipment needing a neutral would be a cloths dryer.the heating elements are 220 but the motor and display is 110.

 

[wyliesdiesels]

What equipment will u be plugging into these outlets?

Personally, i would always run 4-wire, regardless of needs, in case i ever might need the neutral.

 

[Paul-ish]

Air compressor and welder.

Wow... Well that's a relief...

I wouldn't worry about it now.

You only need the neutral "common" for 120v so for your welder and a/c you should be fine.

What kind of "electrician" wired that outlet box? I would be looking at everything he has done, and if he worked for me-he would be now looking for a new job.

I was gonna say the guy put it on 2 separate single pole breakers lol,or is that a 2 pole tandom setup. I don't see a separation in the middle of the breaker only by the screw area
Not to mention the mc connector and it's backwards,box is screwed to side instead of getting a nail on box,just a couple things I can come up with

More than two ground wires under the screw in the ground bar, in the panel. For neutrals its one per screw, grounds its two per screw. This is pretty much the norm as specified by the panel manufacturers. Its a Square D panel.

Box should have been a nail on with flange spot welded to the box for alignment and attachment to the stud. Kinda funky looking device holding the Romex where it passes thru the box. Romex not stripped back far enough, not enough wire (esp the ground) to make a pass around the ground screw in the back of the box and then to the receptacle with lots of slack. I leave enough wire to make a pass all the way around the inside of the box most of the time. This leaves lots of slack to remove or install the receptacle.

Square D double pole breakers are one piece body (actually two halves carefully mated together), one handle, not the two single poles riveted together like other brands.

And the ground screw is not green in the box,and yes I have failed for that before lol

 

[sberry]

I hadn't thought about it but that wire is cool, cant recall ever seeing any.

The ground screw is not required to be green. That is one of the many common misconceptions in the trade.

 

[pattenp]

The only ground screw that is required to be green is the ground screw on wiring devices. NEC 250.126

Those are quad breakers.

 

[pattenp]

Technically the breaker pictured is a Tri-breaker. 2 SP and 1 DP.

Huh?

Hmmmm, Square D/Homeline and Eaton/CH calls them quad breakers...

http://www.homedepot.ca/product/bolt-on-duplex-quad-replacement-breaker-2-1p-15a-1-2p-30a/943154

but that seems to be a regional thing because around here we call them quad breakers unless they're 2 DP with the inner and outer breakers linked, we call those "dual tandem".

I've never heard anyone call them tri-breakers before, must be a regional thing.

 

[sberry]

I cant recall seeing 2 conductor where it want black and white,,, maybe , just don't recall.

 

[jeffmoss26]

I've never seen 10/2 like that either.
I wonder if it's only a Canada thing.

 

[pattenp]

Looks like different manufactures call them by different names. Murry and Siemans refer to the 3 in 1 breaker as Triplex. The DP 2 in 1 is a Quadplex.

The breaker is 4-poles , a quad.
